1 Claim. 1

This invention relates to a Venetian blind structure for windows, and has for its principal object improved means for carrying and receiving the ends of spaced slats removably, said means being end frame members vertically disposed and fastened to a window unit by screws, or the like.

Another object of this invention is to provide a Venetian blind structure of a thickness so that the same may be applied between the screen and the window sash without interference to either, and furthermore the blind structure is void of protrusions or obstructions extending from the sides of the window whereby the general appear ance of the window internally and externally is not noticeably changed.

A still further object of this invention is to provide a blind structure that is preferably made from aluminum and being so positioned externally of the window sash to guard against direct sun rays contacting the window whereby the temperature inwardly of a building is comparatively reduced in hot summer days.

A still further object is to provide a Venetian blind structure having means to slantingly set the blind slats so that the same may serve as a ventilator and guard against rain entering a building.

A still further object is to construct-the invention so that the blind slats may be easily removed in their entirety or separately for cleansing purpose and temporary storing the slats.

A still further object is to provide a vertical rod centrally disposed between the ends of the slats to adjustably set the slats to a partial or closed position.

A still further object is to provide a blind structure that is adapted to a conventional screen or window frame without alteration of said screen and frame.

These and other objects will hereinafter be more fully explained, reference being had to the accompanying drawings forming a part of this specification, and in which like characters will apply to like parts in the different views.

Referring to the drawings:

Fig. 1 is an inside view of a window unit and my invention applied, parts of the window sash being removed for convenience of illustration.

Fig. 2 is an outer or opposite side view of Fig. l, a portion of the screen being removed.

Fig. 3 is an enlarged fragmentary view of the inner side of the window and blind structure.

Fig. 4 is an enlarged cross section taken on line 4-4 in Fig. 1.

Fig. 5 is a vertical section taken on line 5-5 in Fig. 3.

Fig. 6 is an enlarged and fragmentary view of the lower end of Fig. 5 to illustrate the method of rocking the slats.

Fig. '7 is a front view of Fig. 6.

Fig. 8 is a view taken on line 88 in Fig. 6.

Fig. 9 is an inner side View of a window screen with a modified blind structure applied thereto.

Fig. 10 is an enlarged vertical section taken on line Ill-l0 in Fig. 9.

Fig. 11 is an enlarged cross sectional view taken on line Illl in Fig. 9.

The invention herein disclosed consists of a pair of end frame members, vertically positioned and spaced apart to support spaced blind slats I in horizontal position.

It will be seen in Fig. 4 that each end frame member comprises a web 2, a right angle leg 3 for securing the member to a conventional window sash separating stop 4 through the medium of screws 5, or the like. Extending from the opposite edge of said web is another right angle leg portion 6 to serve as means to receive and support the ends of the slats as later described, said portion 6 having an inturned portion 1 to close the frame and to seat on the inner edge of a conventional window screen frame 8.

It will be understood that the frame members of this invention are secured to said stop 4 which is suitably attached in a window frame 9 between the window sash it and window screen frame 8, whereby the slats are positioned in the space between the screening ll and said window sash Ill and II.

The window screen centrally of its upper and lower ends has its usual horizontal bar l2, in which instance the Venetian blind structure is separated into a lower and an upper unit. When reference is made to the invention, the same applies to both units, consequently like reference characters are applied to corresponding parts thereof. It will be noted that the lower unit of the blind structure is principally shown in Figs. 3, 5, 6, 7, and 8 while the upper unit is similarly constructed.

The manner of supporting the blind slats will now be described. As shown in Figs. 3, 4, 5, and 6 a plurality of horizontal slots l2 are made in the web of the frame members adjacent the leg portion 6 to communicate with their respective slanting slots [3 formed in said leg portion 6. Each end of the slats have a spindle l' suitably arranged such as by bending a portion of the end of the slat into a substantial cylindrical form as shown in Fig. 6, said spindle entering the slots [2 to rest in the lower extremity of slots I3, which is provided with an arcuate seat A to permit rotation of the spindle. The slant and arcuate seat of the slots l3 are means to retain the blind slats against displacement and permit rotation of the slats on their longitudinal axis for adjusting the same to a partially or entirely closed position.

To adjust the blind slats is through the medium of a rod [4 that is vertically disposed intermediately between the ends of the slats. Said rod rests against the inner edges of the slats and is removably secured thereto by hooks I5, which are fastened to the rod and adapted to spring outward for their insertion into apertures I6 adjacent the inner edges of the slats. A vertical movement of the rod will cause turning of the slats for opening and closing thereof, and to retain the slats in their adjusted position, it will be seen that the lower extremity of the rod engages through a slot ['1 of a legged bracket I8 and said rod having a plurality of notches I9 to engage the edge !9 of said bracket as shown in Fig. 8. To close the blind slats the rod at its lower end is moved away from the edge [9 and then upwardly to engage a selected lower notch, and vice versa for opening the slats. The rod is retained with respect to its set position by a leaf spring 20 that has one end secured to the bracket while the other end is free to swing outward for disengagement of the notched portion of the rod. To accommodate for the inward and outward movement of the rod by reason of rocking of the slats, the slot I8 is elongated to permit sliding movement of the rod along the leaf spring. In this instance, the bracket is secured to the window frame at its lower extremity by screws 2|, however considering the upper unit of the blind structure such bracket is secured to the upper extremity of the window frame as shown in Fig. 1.

Figs. 9, l0, and 11 illustrate a modified blind structure wherein the same is applied to the inner side of a conventional window screen frame 22, in which instance, when the screen frame 22 is moved from the window unit to which it is applied, the frame will carry therewith the said blind structure. The end frame members to support the blind slats 23 each consist of a web B, a pair of legs C and D extending at right angles from the opposite edges of the web, and inturned bent portions E and F from legs C and D, respectively. Leg C is reduced in width over leg D so that bent portion E may rest upon the inner side of window screen frame 22 and secured thereto by screws 24 that extend through the web and portion E and into the window screen frame, while the other inturned bent portion F engages the inner edge of the window screen frame and adjacent the screen 25 to enclose the frame member as well as to provide for greater strength and appearance. The web adjacent the leg C is notched to communicate with a slanting slot provided in the leg D, by which means, the ends of the blind slats may be inserted in the slots and retained thereby in a slanting position substantially as shown in Fig. 10, This blind structure may be employed wherein the slats need not be adjustable, however the slats may be removed selectively, whereby a portion thereof may remain if so desired, or all slats may be removed by withdrawing the same from their respective slots for cleansing thereof, or for temporary storage, it being understood that the end frame members may remain fixed on the window screen frame.

While I have shown and described the invention somewhat specific, the same may be varied slightly therefrom with respect to proportion and exact details of construction as lie within the scope of the appended claim.

Having fully described my invention what I claim as new and desire to secure by Letters Patent is:

In a Venetian blind structure for a window, said window having a screen and a frame therefor, said Venetian blind structure comprising a pair of spaced frame members vertically positioned, each frame member consisting of a right angle leg and screws to secure the leg to the frame of the window, a web extending inwardly from said leg, a second right angle leg portion extending from the web in the same direction as first said leg, and another flange portion extending from said second leg portion and toward the frame of the window for contacting the screen, said second leg portion having seats in spaced relation vertically, a plurality of horizontally positioned slats carried by the said second right angle leg portion, said slats having spindles on their ends to engage in the seats of said second right angle leg portions, a rod vertically disposed intermediately between the ends of the slats, a hook to secure one edge of each slat to the rod rockably, said rod at its lower end having a series of notches, and a bracket secured to a lower portion of the window frame, said lower end of the rod engaging in the bracket to retain the slats as selectively rocked on a horizontal line.
